Expert Solution

Here one purchases stock of $60, hence it is cash out flow

One purchases put option, hence one has to pay premium of $0.90, hence it is cash outflow

One sells call option, hence one will receive premium of $1.05, hence it is cash inflow

Thus total cost of position = 60 + 0.9 - 1.05

=59.85$
